WATER-RESERVOIR FOR RANGES.

SPECIFICATION formingpart of Letters Patent No. 703,249, dated June 24, 1902.

Application filed June 24, 1901.

T @ZZ whom if may concern:

Be it known that I, GUsrAv HENRY GRIMM, a citizen of the United States, and a resident of Rutland, in the county of Rutland and State of Vermont, have invented a new` and Improved Water-Reservoir for Ranges, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved Water-reservoir for ranges, to insure quick heating of the Water, to aid in the combustion of the fuel, to reduce the generation of steam to a minimum, and to prevent the escape of the steam generated into the room or into the reservoir-casing and range, thus avoiding the formation of a destructive alkali by the mixing of the steam with the soot and ashes.

The invention consists of novel feature and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of my invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional side elevation of the improvement as applied to a range, part of the latter being shown in elevation. Fig. 2 is a sectional plan View of the same on the line 2 2 of Fig. l. Fig. 3 is a plan View of the same. Fig. 4. is a perspective View of the reservoir. Fig. 5 is an enlarged sectional side elevation of the same. Fig. 6 is a perspective View of the damper for the exit of the smoke and gases from the reservoir-casing. Fig. 7 is an enlarged sectional side elevation of a fastening device for securing a drip-pan to the bottom of the reservoir. Fig. Sis a transverse section of the improvement as applied, the section being on the line S ,8 of Fig. l.` Fig. 9 is an end elevation of a modified form of the improvement. Fig. l0 is a sectional plan vieW ofthe same on the line 10 l0 of Fig. 9, and Fig. ll is an enlarged sectional side elevation of a modified form of the reservoir-body.

On the end of the range or stove A opposite to the end on which the :tire-box is located is secured a Water reservoir casing B, into which depends the water-rcservoir C, con- Serial No. 65.817. (No model.)

taining the water to be heated by part of the heat emanating from the burning fuel in the lire-box and passing under the top A/ of the range and over and around the oven A2 in the usual channel to finally pass to the smokeflue A3.

The casing B is covered by a top E, iiush with the top A', and in the top E is formed an opening and a depressed annular seat E for the reservoir C to rest on, as is plainly indicated in Fig. l. The reservoir C consists, essentially, of a body C', of copper or other suitable material, riveted or otherwise fastened to the annular depending flange C2, extending downwardly from the inner end of a horizontal flange C3,terminating atits outer end in a rising annular rim C4, so that a cross-section of the side and end of the rim and flanges C3 C2 is Z-shaped, as will be readily understood by reference to Fig. l. The horizontal flange C3 fits snugly on the seat E', and the rim C is fiush with the tops E and A', and on the said flange C3 rests the reservoir-cover, preferably made in two parts C5 and C, as is plainly indicated in Figs. 3 and 4. A packing F, of asbestos or other suitable material, is preferably interposed between the depending flange C2 and the body C', as is plainly shown in Fig. 5. The upper surface of the top of the reservoircasing is flush with the top of the rim C4, so that when the device is in use the entire upper face of the range and the Water-reservoir is on the same level, thus giving a fine appearance to the range or stove.

The wall D, which separates the interior of the range A from the interior of the reservoircasing B, is formed at its upper end with an inlet D and near its lower end with an outlet D2. The inlet D is preferably formed with a number of apertures arranged in a row and adapted to register with corresponding apertures in a damper G, mounted to slide transversely in suitable bearings formed on the Wall D. The outer end of the slide Gr is provided with a handle' G', adapted to be taken hold ofl by the operator to move the damper G transversely, so as to open and close the inlet DZ The outlet D2 is adapted to be opened and closed by a damper H, mounted to turn in the front and rear Walls of the reservoir-casing B, (see Fig. 6,) and the outer IOG end of this damper H is provided with a suitable handle H', 'under the control of the operator, to turn the damper H, so as to open and close the outlet D2.

Directly opposite the inlet D' is formed a steam-outlet C7 for permitting the steam to escape from the interior of the reservoir C to 'the channel between the inner Wall of the reservoir-body and the Wall D. This steamoutlet is formed by a number of apertures,v

as is plainly shown in Fig. 4, and in order to cause the steam to pass through this outlet it is necessary to provide the top of the reservoir with apertures C8, so that atmospheric air can pass into the upper portion of the Water-reservoir C, and thereby cause the steam to pass through the outlet C7 into the channel previously mentioned.

A protecting-hood C9 is arranged on the inside or' the Water-reservoir C at each opening forming the steam-outlet, so that Water contained in the reservoir cannot splash through the outlet into the channel. Below the bottom of the Water-reservoir C is arranged a drip-pan I, preferably fastened by bolts I to the bottoni of the reservoir-body C', as is plainly shown in Figs. l and 7, suitable spacing-blocks I2 being arranged on the bolts between the bottom and the drip-pan to hold the latter a suitable distance below the bottom of the Water-reservoir C. Any moisture accumulating on the outside of the body C of the Water-reservoir C finally flows down and passes into the drip-pan I, in which the water is evaporated by the heat circulating around the reservoir C Within the reservoircasing B to prevent the said body from rusting. The drip-pan may be otherwise supported below the reservoir.

ln order to assist combustion of the fuel and of the burning gases passing into the reservoir-casing B, it is necessary to introduce atmospheric air, and for this purpose the outer side of the reservoir-casing B is provided near its top With openings B', so that air can pass into the interior of the casing B for the purpose above mentioned.

By the particular arrangement of the flanges on the body O, I prevent steam that is generated within the body C from passing into the interior of the casing B, and I also prevent such steam from passing up into the room in which the stove or range is located. By having the steam-outlet CI and the airinlet C8 it is evident that steam generated in the Water-reservoir passes into the channel at the entrance of the intensely-heated gases, so that the steam is at once dissipated and aids in the complete combustion of the burning fuel.

It is understood that when the dampers G and H are in the position shown in Fig. l the smoke and gases from the burning fuel in the fire-box of the stove or range can pass through the inlet D to the outlet of the casing B, so as to completely surround the body of the Water-reservoir C to heat the Water contained therein, the products of combustion finally passing through the outlet D2 to the channel extending under the oven A2 and to nally reach the smoke-iiue A3. During this passage of the smoke and gases through the reservoir-casing B the drip-Water in the pan I is readily evaporated and carried along With the gases, it being understood that by the entrance of fresh air through the openings B complete combustion is obtained for anyunconsumed gases during their passage through the casing B. Thus bythe arrangement described suiiicient draft is established in the Water-reservoir B, so that the steam, and in fact all the moisture, is taken care of to finally pass With the smoke and gases to the Hue A3, and consequently the steam does not mix with the soot and ashes and forni an alkali, which has proved so destructive in stoves and ranges as heretofore constructed.

The damper G may be dispensed with, and in this case large openings D3 are formed in the Walls D, and on the inside of the said openings are arranged deflectors D5 to cause the smoke and gases to be deiiected away fromthe corners of the Water-reservoirs, as will be readily understood by reference to Figs. 9 and 10.

As illustrated in Fig. ll, the Water-reservoir C may have its top formed of a single piece integral with the body, and in this case the horizontal flange C10 extends integrally from the upper end of the body to be turned over at its outer end to form a seam C11 for containing a Wire C12 to strengthen the rim thus formed by the parts C11 and O12.

In order to insure rapid combustion of the gases and smoke passing over the oven to the damper G and Wall D, I prefer to introduce atmospheric air to the smoke and gases by a perforated pipe J, extending over the corner of the oven A2, at the outside thereof, directly opposite the damper G, the ends of the pipe opening into the room.

Having thus described my invention, I claim as new and desire to secure yby Letters Patentl. A water-reservoir for stoves and ranges, comprising a casing extending from the stove or range and connected .with the interior thereof by an inlet and an outlet for the products of combustion, and a Water-reservoir set .in the said casing and having an air-inlet and a steam-outlet, the inlet for the products of combustion being arranged directly opposite the steam-outlet from the reservoir, and a damper for controlling said inlet, as set forth.
